Fillers are typically injected using a small needle. The procedure is usually performed in a doctor's office or a medical spa. It is a relatively quick and easy procedure, and most people experience only mild discomfort.
The results of filler injections can be seen immediately. The filler will gradually be absorbed by the body over time, so the results will last for a few months to a few years, depending on the type of filler used.
Fillers are a safe and effective way to improve the appearance of the face. However, it is important to note that they are not a permanent solution. The filler will eventually be absorbed by the body, and the wrinkles or folds may return.
